This invention relates to a flushing apparatus of the kind as isprincipally used for flushing the cup of water-closets.

Numerous devices have been proposed for the said use, but most of themgive trouble through vibrations, noises and hydraulic recoils in thewater pipes and chiefly through the very important wasting of watercaused either by the feeding valve that is always unsufficientlybalanced, or by the floater, or by the rubber packing under the mobilebell, or by the seat of the cook or the bell.

In the new apparatus which is hereby presented, the overflow siphon isfixed and the floater valve is dispensed with. It is composed of a boxmade of wood, metal, porcelain, etc., a feeding valve, an inner fixedsiphon and a mobile floating bell.

The outer box, of indifferent shape, has a bottom provided with twoholes, the one for the flushpipe and the other for the feeding valve. Atthe centre of the box, a tube acts as guide to the floating bell and aspassage for the pullchain.

The feeding valve is, in the given example, placed in the axis of thebox, near the inner tube, and it is mounted on a leading stem. Thepriming siphon, whose height and diameter are proportioned to the volumeof the flush, is fixed to the bottom of the box by a jam-nut making atight joint.

The bell, whose weight is calculated to balance the pressure of thewater during feeding, is provided with an inner tube which slides on thetube containing the pullchain.

In order that the following explanations may be clearly understood, anexample of practical realizing of the invention is shown by the annexeddrawing.

Fig. 1 is a transverse section of the complete reservoir during feeding,the valve being kept open by the weight of the bell.

Fig. 2 is a transverse section of the complete reservoir as filled thefeeding valve being closed. The line A-A shows the normal level of waterat that moment. The line 3-3 shows the level of the water at the momentof priming the siphon.

The apparatus Works in this way: the reservoir being empty (Fig. 1) theweight of the floating bell presses through the spur 9 on the stem I ofthe valve, which is thereby kept removed from its seat permittingarrival of water through the aperture II and the conduit I2.

As the water rises in the reservoir, it compresses the air of the belluntil the resulting pressure balances the weight of the bell. From thatmoment, the bell rises with the water, freeing gradually the stem of thevalve, which is pushed towards its seat by the pressure of the water.-At the moment the bell has reached its level, the 10 valve is pressedon its seat, intercepting completely the passage of water. The water hasthen reached the level AA' of Fig. 2 and the reservoir is ready for use.To produce a flush, one has only to depress the floating bell. In theexample,

I that is done by a pull at the chain. As the floating bell descends, itmakes the water rise to the level B--B where it flows over in the siphonwhich is thereby primed. The resulting flush empties the box. Refillingof the box begins at once as the floating bell is pressing through itsspur on the stem of the valve giving inlet to a new volume of water.

It is well understood that the above described reservoir is given as anexample and that it may, in the limits of the invention, be modified indifferent ways or adapted to other uses. For instance, the shape of thebox, of the floating bell and of the valve may be modified, the valvehaving the shape of a disc, a conus, a ball, etc. The 0 descendingmovement of the floating bell may be produced by any other means thanthe chain described above. In some cases, the inner leading tubes may bedispensed with; for instance, when the reservoir is placed low so thatthe floating bell can be actuated by pressure exerted on its top.

What I claim and desire to secure by Letters Patent is:

In a flushing apparatus, the combination of an outer reservoir, afeeding pipe with a lifting valve,

a fixed siphon with a flushing pipe, a float open at its undersideactuated directly by a pullchain and rising with the incoming water,means for stopping said float at a predetermined level, said floatcausing the siphon to be flooded on being actuated by said pullchain andmeans for opening the feeding valve just before reaching the lower limitof the downward travel of said float.
